The competition between luxury cars is more than just a “regular option†for size, displacement, performance. Because customers are more critical than ordinary family car users, the competition between products is reflected in all aspects, such as the sound system that many people attach great importance to. The recent launch of the Cadillac XTS is highly sought after, and it is closely related to its well-received BOSE sound, in addition to its leading technology and outstanding performance. It is worth mentioning that the XTS is equipped with the top audio brand BOSE, which creates a “mobile theater level†listening experience, which is more generous than the “Analog†of the Audi A6L and BMW 5 Series. a lot of. So, what is the secret of the Cadillac XTS sound?
Mystery 1: Tailored BOSE 
Car audio and home audio are essentially different. This is mainly due to the special environment inside the car. Home audio, as long as the sound is pure, the ideal sound field reduction can be achieved by simple two-channel display. The interior of the car is not. The small space, complicated interior materials, and relatively fixed seating settings all place high demands on the sound design. In order to obtain accurate sound field positioning in such an environment, it is necessary to rely on a precise design and matching of the entire car audio system.
BOSE is different from other audio brands that have been transferred from the home audio field. It started with the car audio in the 1980s and adopted a model developed in cooperation with auto manufacturers. From the development of a car, BOSE engineers are involved. The engineer will calculate and design the position of the speaker, the output of each channel according to the shape of the space inside the car, the path of the sound reflection, the selection of the interior material, and the optimal positioning of each seat through digital surround technology. Sound restoration. This tailor-made, so that the sound is no longer simple is just a configuration of the car, but like the engine, the transmission and the whole car.
Tailor-made is a tacit understanding of cooperation. When BOSE started to get involved in car audio in the early 1980s, the choice was to develop with Cadillac. The 30-year cooperation has undoubtedly formed a combination of Cadillac XTS and BOSE sound, which laid a solid foundation for perfect sound.
Mystery 2: Bose Centerpoint® Surround Sound Technology 
As the latest collaboration between BOSE and Cadillac, Cadillac XTS's audio undoubtedly reflects the latest level of BOSE sound technology, such as its Bose Centerpoint® surround sound technology.
The beauty of Bose Centerpoint® surround sound technology is the 360-degree sound field reduction with up to 14 speakers and Bose SurroundStage® signal processing circuitry, giving every rider a theater-quality listening experience. An XTS owner of a senior enthusiast has said that listening to the symphony in the Cadillac XTS can feel the position of different instruments, and the sound field is positioned as much as the HI-END fever audio in his home. 
To do this, BOSE's engineers are hard-working. For example, engineers have innovatively installed a Bose Personal® personal speaker on each side of the front seat headrest, allowing the listener to get the sound signal in the most ideal way. At the same time, the True Space® digital processing circuit creates a more spatial sound field.
Mystery 3: epoch-making Bose ANC active noise reduction mute technology 
In addition to the limitations of space and interior materials, another important factor in the car's listening environment is the noise inside the car. Such as tire noise, wind noise, engine noise and so on. Most of these noises are medium-low frequency noise of 100-1000 Hz, which not only affects the comfort of the driver and passengers, but also interferes with the mid-low frequencies that are most difficult to perform in the sound reduction, thus greatly reducing the listening quality. In the past, in order to get more rational mute and listening effects, engineers even had to compromise on performance – knowing that engine hardening will inevitably increase noise.
Another major innovation of BOSE's cooperation with Cadillac is the use of active noise reduction to achieve noise control innovation. This technology uses a sound wave that is opposite in phase to the noise source through the speaker to achieve "virus attack", which completely cancels the noise. BOSE has applied this technology to the famous BOSE noise canceling headphones and gained a high degree of recognition. This BOSE overcomes more technical obstacles and applies this technology to the Cadillac XTS, which also achieves almost magical effects.
Eliminating noise through such electronic technology not only surpasses traditional sound insulation in terms of noise reduction capability, but also allows automotive engineers to have more room to play. For example, Bose ANC can effectively offset the noise of the engine, so engine engineers can let go of their hands and feet for performance design and adjustment. To some extent, the Cadillac XTS 2.0T engine and 3.6L engine both became the same power champion, and Bose ANC also contributed.
in conclusion:
Bose's position in the audio field, BOSE sound tailor-made model, combined with Cadillac and BOSE for 30 years of cooperation, ultimately achieved the Cadillac XTS beyond the imagination of the sound performance. It is worth mentioning that the Cadillac XTS sound system can not only enjoy the music enjoyment of the enthusiast level, but also the rear-line 8-inch dual-screen audio-visual entertainment system and Blu-ray DVD that can be independently enjoyed. The home theater is also found in the back row of the Cadillac XTS. feel.
